3. 3 2. Commodity Exchange Act Exemption Market Participant Risk Management Capability Verification Participants and ISO/RTOs have expressed interest in developing common risk management standards and processes for use in all markets. –ERCOT supports harmonization but this will depend on the outcomes of stakeholder processes. ERCOT staff are working with counterparts at other ISO/RTOS to develop common approaches to participant standards and verification processes. The CCRO has a group working on development of risk management standards. ERCOT staff are providing input to the work group but the outcome will not be binding on ERCOT or other ISO/RTOs.

5. 5 2. Commodity Exchange Act Exemption Market Participant Risk Management Capability Verification How should verification be done ISOs are looking into the possibility of contracting the verification process out to one or more third parties. –Ideally, each CP would have only one review that would be good for all ISO markets (e.g. passport) Logistical issues are being reviewed to determine feasibility Regardless of whether or not a third party is used, ERCOT will maintain ‘ownership’ of the results. –If a third party is used, ERCOT will likely provide a final review and determination of adequacy for the ERCOT market Finance and Audit CommitteeMay 16, 2011

7. 7 2. Commodity Exchange Act Exemption Central Counterparty Update As previously noted to the Committee, ERCOT expects to seek Central Counterparty (CCP) status. ERCOT external counsel has indicated that, in their opinion, establishment of a CCP would be the cleanest way to ensure set- off across Day Ahead and Real Time markets in the event of bankruptcy. –While ERCOT and its external counsel believe becoming a CCP will enhance its position in bankruptcy, no ISO has yet tested this in bankruptcy court Finance and Audit CommitteeOctober 17th 2011

8. 8 2. Commodity Exchange Act Exemption Central Counterparty Update Considering the potential risks and alternatives, ERCOT staff does not believe that becoming a CCP will significantly increase risk to ERCOT, Inc. or its Market Participants. A subgroup of the CWG continues to explore the potential benefit to Market Participants of using a 3 rd party as a CCP Finance and Audit CommitteeOctober 17th 2011
